Here's what Westside has to say about the Adder:

The Adder is ready to bail disc golfers out of the windiest of conditions. With high speed and a pop top giving good glide, only the biggest arms will have a chance to make this disc turn over. For everyone else, it will be a very useable utility disc for when you need a distinct fade with speed through the flightpath.

Speed: 13 Glide: 5 Turn: 0 Fade: 4
